Fastening of the Drill Rig
Fastening by means of dowels in concrete
Fastening of the drill stand by means of a vacuum plate
(as accessories available)
Don't use the vacuum mounting on the wall and overhead!
For a low-pressure mounting the surface which is to be drilled must be not
porous and must be flat and free of cracks.
If this is not the case, this kind of mounting can't be use. For the vacuum
mounting you need a vacuum pump, a vacuum plate and vacuum hoses
(see illustration). These items are available on request.
For brickwork, Rawl-Dowels
must be used.

Mark the position of the drill holes for the fastening
on the surface to be drilled.

Drill a hole (Ø 15) 50 mm deep (A), into which the
dowel M12 (B) is to be placed; insert and secure
the dowel with the doweling tool (C).

Screw the quick action clamping screw (D) into
the dowel.

Install the drill rig.

Fix the washer (E) and finally the fastening nut
(F) on the quick action clamping screw (D).

Tighten the fastening nut (F) with a wrench SW
27.

Before and after tightening the nut (F), the 4
adjustable screws have to be adjusted in order
to adapt the rig to the surface.
Do check whether the drill rig is
installed safely and firmly.
